T all whom it may concern:

Be it known that I Momus W. PooL, citizen of the United -of the borough of Brooklyn, cit of New York, in the county of Kings an State of New York, have invented certain new and useful Improvements in Typewriting Ma-- late to a modification of the invention disclosed in my application Sr. No. 470,818, filed May 19, 1921. In said application provision is made for moving the work carrying element relatively to the printing in- Strumentalities in order to provide sufiicient room to facilitate the adjustments of the work sheets. Bymy present invention a space or gap for this purpose is provided by bodily moving the printing instrumentalities as a unit away from the paper holder or carrying element. 5

1ward in the direction of the arrow at said Figure 5 is a perspective view of a part here nafter described as a bracket or support ng member.

F1gure 6 is a fragmentary perspective view of a modified construction.

As shown in Figuresl, 2 and 3 there is provided a base or supporting member 1 wh ch may be of wood or other suitable ma. terial and which supports a track or guide member comprising a horizontal plate-like base portion 2 and upright side portions or bars 3', said member being out out as indicated at 4 for the sake of lightness and being secured in any suitable way to the base 1 as by screws 5. Each bar 3 is provided with cutouts or openin s indicated at 6 near its front and rear, sai openings being generally rectangular but formed at their lower sides with depressions or seats 7, the depressions being connected by a straight horizontal portion 8 which together with the depressions 7 constitutes a runway or trackway. (Jo-operative with each trackwayT, 8 is a grooved roller 9 bearing on a screw pin 10 which is threaded into a block 11 which in turn is secured as by rivets 12 to a T shaped bracket 13, thehead whereof is in I turn fixed by screws 14 to the typewriting machine proper. In the present instance the typewriting machine preferably is con-' stituted by two separate parts or unitary structures, one, the printing or type bar unit, and the other the paper carrying unit. The type carrying unitary structure is housed in and supported on a frame which comprises a base 15, side plates 16 secured to the base, and a top plate 17 surmounting the side plates, the three. portions being suitably secured together to provide a rigid frame or housing. The base portion 15 which may be of cast metal and U-shaped has the T-sha ed brackets 13 secured to the inner faces 0 its side walls by the screws 14 so that said brackets and the pivotal supports '10 of the wheels or rollers 9 are rigid with the type carrying frame 15, 16; 17 said frame and the parts supported on it being thus mounted to roll on the stationary trackways or edges 7, 8, as when pulled or pushed by the operator. The construction is such that the type carrying frame has a limited fore-and-aft movement on the trackway, the

vertical end portion of the opening 6 constituting stops which co-operate with the wheels 9 to limit such movements, and the stops being so related to the depressions 7 that the wheels are seated in the depressions when thus arrested. To insure the retention of the wheels in their seats or depressions 7, until it is desired to shift the type carrying unit from one of its predetermined positions to the other, spring detent devices 18 may be provided to co-operate with the wheels 9 to exert sufiicient pressure thereon to prevent their accidental unseating from the depressions 7. Thetype carrying unit contains and supports not only the type bar system but also the ribbon mechanism, parts of the escapement and tabulating mechanism,'as well as other appurtenances, all of which are preferablyof the general construction disclosed in my aforesaid application Serial No. 470,818 and which for, present purposes require only a brief description. The type bars 19 constituting the aforesaid type bar system are of the front strike. va-

riety, the set or system of type bars being arranged in an arc of a circle and plvotally mounted on a pivot wire 20 which is sup- 'ported on an inclined segment or support 21 fixed to the side plates 16. The. type bars are arranged in guide slots 22 formed in said segment and are normally supported near their free ends by a curved rest 23 which is supported from the top plate 17. Each type bar is formed with a cam slot 24 by whlch it is connected with a train of actuating devices comprising a pin 25 engaging in said slot and projecting laterally from the upwardly extending arm 26 of a bell crank lever which further comprises a short arm 27. Said bell crank is pivoted on a pivot wire 28 common to .all of the bell cranks and mounted on a stationary support 29 carried b the frame member 15, 16, 17 and provide with slots 30 wherein the bell cranks are received. Links 31 connect the short arms 27 with keylevers 32,- the system of key levers being pivoted in the rear of the base portion 15 on acornmon pivotal support 33, each lever having a key 34 providing a keyboard at the front of the frame portion 15. The type bars 19 are each furnished with a single type 35 but it is to be understood that if desired a plurality of types on each type bar may be employed in association with suitable case shifting mechanism.

The types 35 are adapted to print through the printing portion of a ribbon which is preferably controlled by vibrating mecha nism and fed by ribbon feeding mechanism of the general character referred to in my prior application, the ribbon feeding mechanism comprising a ribbon driving shaft 36 which is horizontally arranged and is rotatable from the spring drum or motor mechanism of the machine through a train of devices comprisin a beveled pinion 37 on said shaft 36 which pinion meshes with a beveled pinion 38 rigid with a ratchet wheel 39 that is impelled by a spring pressed pawl 40. The ribbon drivin shaft 36 may be supported from the si es of the machine frame. The pinion 38- and ratchet wheel 39 are preferably mounted on a vertlcal shaft 41 which. is supported on a bracket member designated as a whole by the numeral 42 and most clearly shown in Fig. 5. Said bracket member referably is made of a sin le piece of metal cut out and bent to the s ape shown. The shaft 41 bears at its upper end in a bearing 0 ening indicated at 43 formed in the fore-an -aft central portion 44 of said bracket. Lateral branches 45 are extended from saidcentral portion and bent to provide a rectangular frame part, the ends of which are suitably connected. A bearing or thrust block 46 is fixed to the lower side of said rectangular frame part as by screws 46, the lower end of the shaft 41 bearing in said thrust block 46. Behind and parallel-with the branches 45 a pair or lateral branches or arms 47 extend from the central portion 44, these branches 47 having downwardly bent end portions 48 which terminate in inwardly extending ears 49 that are secured by screws.

50 to a channel-like cross bar 51 arranged transversely of the base and secured at its ends b screws 52 to thickened ortions 15 of t e base, the screws 52 being t readed up through the central web of the channel 1nto tapped holes in said thickened portions 15*, as clearly shown in. Fig. 2. The bracket member 42 is thus secured to the base 15. and provides a support which is rigid with said base. The'front end of the central portion 44 is inclined downward and forward and is secured by a screw 53 to the support 29, thus additionally securing the bracket 42. The bracket 42 also provides a su port for a motoror spring drum mechanism which comprises a drum or casing 54 and a large beveled gear wheel 55 arranged above the casing 54, said casing and said gear wheel being mounted on the shaft 41 and being constantly urged in rotary direction by a main sprlng of ordinary construction housed within the casing 54. The pawl 40 is mounted on the top of the gear wheel 55 so as to co-operate with the ratchet wheel 39 to turn the latter during printing movements of the paper carriage. Constantly meshing with the hortzontally arranged gear wheel at its-rear side is a vertically disposed beveled pinion or smaller gear wheel 56 which ismounted near the rear end of a horizontally dis )osed shaft 57, said shaft extending forwar and being supported on the bracket 42, a forward bearing 58 for said shaft being formed in the block 46. The rear end portion of the shaft 57 is rovided with a key 59 and the key portion of the shaft bears in a rotary bushing or sleeve 60, said bushing being cut out as indicated at 61 (Fig. 5) to accommodate the key portion of the shaft, the two parts having a slidable engagement and being adapted to rotate together. The bushing or sleeve 60 is formed with a groove or circumferential depression 62 which bears in an opening formed at the lower end of an arm 44 which is in effect a downward or angular extension of the central portion 44 of the bracket 42. The

beveled pinion 56 is mounted on theshaft 57 wheel may be countersunk at its rear side to partially seat the bearing sleeve 60. The rear portion of the shaft 57 accomodates a two-part clutch, the forward clutch part 66 being keyed to the shaft by the key 59 so that it' is always compelled to turn with said shaft. Said clutch part 66 is provided at its front side with a flange 67 and is constantly urged rearward alongthe shaft 57 by a forked leaf spring 68 which is secured at its upper end by a screw 69 to the bracket.

member 42, the lower or forked end of the spring loosely embracing the shaft 57 and presslng against the flange of the clutch part 66. The rear of said part 66 is provided with clutch. teeth which normally mesh with corresponding clutch teeth formed at the front face of the second clutch part 7 0, said second clutch part being formed integral with and providing the'hub portion of a beveled gear wheel 71 which provides a connection with the traveling paper carrying element as hereinafter described. The clutch part 70, 71 may bear on a reduced rear end portion of the shaft 57 which provides a shoulder on the shaft preventing forward displacement of said clutch part. A collar 72 pinned or otherwise secured to the shaft behind said clutch part prevents rearward displacement of the latter. The construction also prevents endwise movement of the shaft 57 when the clutch part is held. It will be understood that the bodily fore-and-aft movements to which the frame 15, 16, 17 are subjected are participated in by the bracket member 42 and by the parts carried by said bracket member including the spring drum and its casing 54. the intermeshing gear wheels and 56, the escapement wheel 64, the sleeve and the clutch part 66, such of these parts as are mounted on the shaft 57 moving on and relatively to the shaft, which together with the gear wheel 71 will not affect it by such fore-and-aft movements.

(lo-operative with the escapement wheel 64 is an anchor escapement member 73 provided with teeth or detents 74 and 75 which are adapted to co-operate with the teeth of the wheel 64 at one side thereof. The anchor member '73 is provided with a hub portion 76 which fits over the rear end of a rock shaft 77, said shafthaving as its rear bearing an inward projection 48 from one of the bent portions 48; The hub 76 is provided with a key pin 76 which engages in a longitudinalway or groove 7 7 a formed in the shaft 77, the construction insuring that the anchor member 73 shall participate in rotary movements of the shaft 77' while permitting endwise movements of the member 7 3' along the shaft. The forward endportion of said shaft 77 bears in a bearing opening indicated at 78 in the block 46. The shaft 77 projects forward through said block and itsprojecting end receives the hub portion 79 of a crank arm 80 which is secured to the shaft 77 by a pin 81 passing through the hub. The crank arm 80 projects' horizontally outward or leftward and at its outer free end is connected by a de--.

pending link 82 with the free end of a crank arm 83 which is fixed to and extends for ward from a rock shaft 84 arranged transversely of the base 15 and taking bearings at the sides thereof. Said rock shaft is provided near its ends with forwardly extending crank arms 85 which are suitably fixed to said shaft and are slightly inclined downward therefrom, the free ends of said crank arms being connected by a cross bar; 86

which underlies the key levers and is adapted to be operated by them when they are depressed, said cross bar acting as a universal bar for the escapement mechanism. It will be understood that when one of the printing keys 34 is operatedto cause its associate type bar 19 to print, the actuated key lever 32 will depress the universal bar 86, rocking the shaft 84 and swinging the crank arm 83 downward, such downward movement being transmittedthrough the link 82 to the-crank arm 80 which will rock the shaft 77, causing theanchor member 73 ,to co-operate with the escapement wheel to afford '.a letter space feed' movement of the carriage on the completion of the oscillatory movement of the anchor member, the impulse of the spring drum being transmitted the paper earrying element through the-- train of connections comprising the clutch parts 66 and 70 andthe gear wheel 71. From what has been said it will be understood that mechanism are not interfered with, such mechanism normally maintaining the printing portion of the ribbon below the printing point but at each type bar actuation operating to interpose the printing portion of the ribbon in the path of the actuated type bar 19 so that said type bar is caused to rint through said ribbon; and that the rib 11 receives a feeding impulse or advance movement at each type bar actuation, due to impulses transmitted through the gear wheel 55, pawl 40, ratchet wheel 39 and intermeshing pinions' 38 and 37 to the ribbon driving shaft 36 and thence in alternation to the ribbon spools which are not shown herein but which are adapted to be connected with the ribbon driving shaft in the manner more fully explained in my said prior application.

eferring next to the work carrying devices, as appears from Figs. land 4, posts 87 rise from the sides of the plate-like base 2 at its rear, said posts supporting trans versely extending parallel trackways 88 which are oppositely grooved to receive anti-friction rollers 89. The rollers 89 also co-operate with a pair of oppositely grooved rails 90 which are part of the structure of the traveling carriage or work carrying element, said carriage further comprising uprights in the form of angle bars 91, the'rails 90 providing cross bars connecting said uprights 91, and thewhole constituting arigid carriage frame. Secured to the front of, this frame as by rivets 92 is a plate, table or flat paper holder 93 providing an upright vertically disposed work-receiving plane surface which preferably is. formed at Its upper part with a transversely extending slot indicated at 94 for the accommodation of a rotary platen 95. Said platen may be of ordinary construction and is arran ed behind the flat paper'holder or table 93 ut projects forward through the opening or slotway 94 so that the front or printing face of the platen is substantiall in the plane of said table which is also t e printing plane of the paper. For the sake of clearness the extent of forward projection of the platen through the table is exaggerated in Fig. 1. The axle portions 96 of the platen bear in the side portions of the angle bars or uprights. 91 and at their ends are rovided with the usual finger Wheels or twir ers 97. Mounted on the right-hand platen axle 96 inside the side portion of the upright 91 is a line spacing ratchet memes wheel 98 with which is adapted to cooperate a line spacing pawl 99 ivoted at 100 on a pawl carrier 101 which is loosely mounted on said platen axle. The pawl 99 is angularly shaped and the arm opposite from its engaging portion or tooth has pivotally connectedto it at 102 a link 103 which extends upward and at its upper end is pivotally connected at 104 to a crank arm 105 fixed to the rear endof a rock shaft 106. Said rock shaft which bears in a hearing or housing 107 rigidly mounted on the righthand angle bar 91, extendshorizontallv forward terminating in a downwardl extending handle or finger piece 106. t will be understood that when the shaftv 106 is rocked by its handle it operates to swing down the crank arm 105, this motion being transmitted through the link 103 to the pawl 99 which is initially thrown into engagement with the ratchet wheel 98, subsequently operating, as the pawl carrier 101 is rotated downward, to turn the ratchet wheel and communicate a line spacing rotary move ment to the platen 95. Suitable detent devices (not shown) co-operate with the ratchet wheel to hold the platen against accidental turning movements. The handle 106* also serves as a convenient means for restoring the carriage from left to right along its guide rails after the completion of a line of writing. Connections between the carriage and the carriage motor or spring mechanism of the machine are provided by "an angular or beveled rack bar 108 which is secured to the front face of the table 93 and extends transversely thereof, the inclined 'face of said rack bar being formed with teeth which co-operate with the teeth of the beveled. gear wheel 71. The rack bar 108 and gear wheel 71 are maintained coustantly engaged or intermeshed by means of anangle bar 109 which is secured to the top of the toothed bar 108 and has a down 'wardlyextending ortion which lies forward of the gear w eel 71 in such position as to prevent, in allpositions of the carriagei a forward displacement of said gear whee. The construction is such that the gear wheel cannot be displaced axially in either direction. It will be perceived that the impulse of the spring drum will be transmittedthrough the shaft 57 gear wheel 71 and feed bar 108 to the carriage, and constantly tends to urge the carriage leftward on its guide bars, permitting leftward step by step or letter feeding movements under the control of the escapement mechanism in the manner hereinbefore described.

Tabulating mechanism as in my prior application may be provided, said tabulating mechanism comprising a toothed tabulator bar 110 which is arranged at the lower end of the carriage, being secured to brackets 111 fixed to thecarriage, said bar 110 accom'modating adjustable column stops 112 co-operati'ng with one or more relatively stationary key controlled stops, which as hereinafter described effect also the release of the carriage from its escapcment devices.- The carriage is adapted to be released not only by the tabulating mechanism but also by key controlling devices on the carriage, said devices comprising a cross bar 113 which is carried by angular arms 114 pivoted at 115 to the associate uprights 91 and adapted to vibrate to an extent determined by stops 116 projecting laterally from one of said uprights at opposite sides of the associate'arm 114. The release bar 113 normally lies behind and just out of contact with the flange 67 of the clutch part 66, the arms-114 being adapted to be turned on their pivots to swing the release bar forward against the flange 67 so as to overcome the spring 68 and slide the clutch part 66 forward on the shaft: 57, disconnecting it from the gear wheel 71 whic'h' is thereby released from the control of the carriage escapement devices. 'The means for causing releasing movements of the bar 113' comprise a crank arm 117 concentric with, and rigidly connected to, one of the angular arms 114, said crank arm being connected with a release key, not shown, by devices comprising a link 118.

The paper feeding and controlling devices include angular paper fingers arranged at the sides of the table 93 and each comprising an upright portion or paper finger proper 119 provide with a pressure roll 120 cooperative with the platen 95 near its ends and along the printing line. The paper fingers are provided with horizontal angular portions 121 which extend to the sides of the table 93 and thence are bent rearward at right-angles, providing side portions 122 outside the uprights 91. The forward portions of the parts 122 receive headed pivot screws 123 which are secured in angular brackets 124 fixed by screws 125 to the table 93. Draw springs 126 connected to the arms or parts 122 tend constantly to turn the paper finger members on their pivots 123 and maintain the pressure rolls 120 opera tively against the platen or the paper thereon. The upright portions 119 of the paper finger members are punched to provide forwardly bent finger portions 119 which serve as convenient finger pieces for releasing the pressure rolls. Below the paper fingers there is provided a paper guide bar 127 which extends transversely of the table 93, said uide bar being mounted at its ends on angu ar arms 128 pivoted at 129 to the sides of the uprights 91, said arms, 128 preferably having rearward extensions which are connected by links 130 with the. paper finger members so that actuations of the keys or finger pieces 119 to release the pressure rolls 120 will also throw the guide bar 127 forward away from the table 93, said table being thus cleared or left unobstructed substantially throughout its front surface, en-

abling the work sheets readily to be adjusted thereon. WVhen separate work sheets are employed of the character illustrated in Fig. l and designated a, b and c, any of them may be dropped against the top horizontal portion of the bar 109 which serves as a con venient ledge or stop for the purpose. The upper ends of said sheets, after passing the printing point, may be guided by angular fingers 131 which are secured by screws 132 to the upper end portions of the uprights 91.

(lo-operative with the tabulator column stops 112 is a tabulator frame stop which in the present instance comprises a tabulator key lever arm 133 provided with an ordinary key cap and stem at its front end, the rear end of said arm 133 being fixed to a rock shaft 134 near its right-hand end, said rock shaft bearing in the sides of the base 15. Fixed about centrally to said rock. shaft and extending rearward therefrom is a tabulator stop lever arm 135, the free end whereof is adapted to co-operate'with the column stops 112 though normally lying below the paths of said stops. When the tabulator key is depressed the lever arm 133 rocks the shaft- 134 causing the arm 135 to swing upward and bringing the stop portion thereof into the paths of the stops 112. The operation of the tabulator lever member 133, 135 also effects the release of the traveling carriage from its escapcment mechanism preferably by a train of connections which throw the anchor member 73 temporarily out of engagement with the escapcment wheel 64.

Said train may comprisea crank arm 136 fixed to the rock shaft 134 to the left of the arm 135' and extending upward from said rock shaft. A link 136 connects the crank arm 136 with the downwardly inclined arm of an angular lever 137, the other or upwardly extending arm whereof is bifurcated or forked, the bifurcated portions 138 engaging loosely in a circumferential groove 7 6 formed in the hub of the anchor member 73. The angular lever 137 is pivoted at 137* to an angular bracket 51 secured to the top of the cross bar 51. The depression of the tabulator key rocks the shaft 134, as has been stated, causing the crank arms 136 to swing forward, this movement being transmitted through the link 136 to the angular lever 137, compelling the forked or bifurcated end portion 138 thereof to swing rearward which movement results in the sliding of the anchor member 73 rearward along its supporting shaft carrying the member 73 out of engagement with the escapcment wheel 64. The parts are timed so that the consequent releaseof the carriage from the control of its escapcment mechanism and its lever 133, 135 and the proximate column stop 112. \Vhen the tabulator key is released the parts including the anchor mem-, ber 73 will be restored to normal position by the usual or suitable springs. Independent movement. of the anchor member 73 lengthwise of the shaft 77 may be limited by contact of the key device 76 with the ends of the slot 77", said key device preferably being in the form of a pin driven through the hub 7 6 to a suflicient extent to project part-way into the groove 77.

In collating work where it is desired relatively to adjust a plurality of work sheets. such as the comparatively long and wide record sheet 0, the shorter bill sheet a and the interposed carbon 1) shown in the drawing, the operator need only' pull forward or toward himself the type bar supporting frame or unitary structure comprising the frame 15, 16, 17 and the parts mounted thereon from the full line position to the dotted line position of Fig. 1. This movement of the type bars and their supporting frame is in a direction substantially at right-angles or perpendicular to the writing or printing plane of the paper and also at right-angles to the path in which the carriage moves transversely on its fixed guideways. The result is that the printing and paper carrying units are spread apart or separated so that a gap or space is provided between them suflicient to enable the work sheets to be conveniently manipulated and adjusted on the collating table or plate 93. Said plate, of course, should be preliminarily cleared by releasing the paper controlling devices. When the unitary structure is pulled or slid forward, as has been described, by the hand of the operator applied to any convenient part thereof, the bracket 42 will, of course, move with it, and the parts mounted or carried by said bracket will participate in such movement, with the exception of the shaft 57 which will remain stationary, held by the gear 71, and will maintain its connection with the carriage, the key 59 permitting. the gear wheel 56 and the escapement wheel 64 to slide forward along the shaft 57 without obstruction. When the type bar unitary structure has been moved bodily forward, as has been described, it will be retained in the abnormal position with the wheels 9 accommodated in the forward seats 7 by its own weight assisted if need be by the detent devices 18, so that both hands of the operator will be free to effect the necessary paper adjustments and manipulations.

After the work sheets have been collated or adjusted as desired, the paper controlling devices are released so as to hold the sheets in proper relationship and then the type bar structure is pushed back to normal position, that is, to the full line position in Fig. 1, after which the writing may he proceeded with until the desired entries have been completed.

A modified construction adapting the invention to use with fan-fold sheets is illustrated in Fig. 6 wherein the fan-f0ld sheet is designated'by the character d. In the modified construction the plate-like bar 2 is formed at its sides with lateral extensions 139 from which rise posts 140 to which are secured extended grooved trackways 141. These co-operate as before with the carriage rails 90 through anti-friction rollers but the construction provides for an extended run of the carriage without obstruction of the fan-fold sheet d by the side supports 140 of the stationary guide rails, these supports being spaced apart sufficiently to permit of a complete transverse movement of the carriage without bringing the side edges of the fan-fold sheets into contact with said supports or posts. To accommodate the fan-fold sheets which ordinarily are continuous or extended strips, the table 93 is provided with a slot indicated at 142 and secured to said table behind the slot is an inclined-paper deflector 143 over which the continuous fan-fold sheet or blank may be led up from the rear of the machine, thence passlng through the slot 142 and up at the front side of the, table or paper receiving element 93. An ordinary severing device for severing the sections'of the strip d is preferably arranged near the top of the table 93.

Variousother modifications and changes will suggest, themselves to those skilled in the art by which the principles of my invention may be adapted for use in connection with different kinds or forms of typewriting and particularly of commercial typewriting.
